The Nebulosity of NEBS Level 2 - Inverters For Data Centers

Equipment that meets Network Equipment-Building System (NEBS) standards has been around for about 50 years. It all started in the 1970s, when Bell Labs developed a set of equipment operating standards to standardize unit implemented in American Regional Bell Operating Companies (RBOCs).

Now owned by Nokia and known as Nokia Bell Labs, Bell Labs has always been a leader in telecommunications technology, so it's not too surprising that NEBS certified equipment has been most used by telecommunications companies for most of its existence. Today, this certification has made its way to new industries that needs what NEBS certification offers. The data center industry is one of these industries.

NEBS Level 2: What Does it Mean?

There are three levels of certification, which Wikipedia defines as follows: Level 1, which "addresses personnel and its safety requirements of GR-63-CORE and GR-1089-CORE"; Level 2, which "addresses equipment operability in a controlled environment (usually data centers) that will not be subjected to environmental stress"; and Level 3, which "meets all of the requirements of GR-63-CORE and GR-1089-CORE [and] has strict specifications for fire suppression, thermal margin testing, vibration resistance, [and more]".

So, it appears that Level 2 is the NEBS certification you would want for power inverters and power converters in data centers. However, after defining Level 2, Wikipedia goes on to note that, "Because of ambiguity, this level of certification is rarely (if ever) used."

If NEBS Level 2 certification is seldom used, why does it exist? The answer is twofold: "NEBS Level 2" is important piece of terminology because it refers to its unit for data centers, while what the term quantifies to is defined by customizations a unit manufacturer implements to address the needs of a specific data center.

In other words, when a data center needs a NEBS inverter, the inverter is ideally custom made to address the particular "controlled environment" of the company. On its own, Level 2 certification is nebulous at best, but when NEBS Level 2 equipment is customized, the conditions the equipment is designed to accommodate are quite clear.

Conclusion

Data centers that need equipment for their respective operating environments should work with a manufacturer that customizes NEBS component for data centers. If your data center needs power inverters, power converters, or another type of NEBS certified equipment, contact a manufacturer specializing in NEBS equipment for your area of need: a data center environment.
